What is Claude?
Claude is Anthropic's family of large language models, accessed via claude.ai (the web app) and the Anthropic API. The free tier gives Claude Sonnet access with daily limits; Claude Pro ($20/month) raises those limits and unlocks Projects (private knowledge bases with persistent context). Claude Max ($100-200/month tiers) offers premium quotas plus access to the latest Opus models.
Claude's headline strength is reasoning quality: it leads or co-leads benchmarks for math (MATH, AIME), code (HumanEval, SWE-Bench), and complex analysis. The 200K context window handles entire codebases or book-length documents. Artifacts (interactive code/document panels) ship inline in conversations. Computer Use (in beta) lets Claude operate a virtual desktop on your behalf.
The API priced at $3/M input + $15/M output for Sonnet tier — competitive with OpenAI. Main constraint on the consumer side: no native image generation (only image input), and the free tier hits limits faster than ChatGPT's.

FAQ
Is Claude free?
Yes — claude.ai has a free tier with daily message limits. Claude Pro ($20/month) raises those significantly.
What's the context window?
200K tokens — roughly 150K words or 500 pages of text.
Can Claude generate images?
No — Claude accepts image input but does not generate images. Use ChatGPT, Midjourney, or DALL-E for generation.
Is Claude better than ChatGPT?
For reasoning-heavy and long-document tasks, often yes. For voice, image generation, and broad tool integration, ChatGPT leads. They're complementary.
Who makes Claude?
Anthropic, an AI safety lab founded in 2021 by former OpenAI researchers, headquartered in San Francisco.
